Operation Chorus

Operation Chorus (13-17 July 1950) was the codename given to the United Kingdom Royal Air Force's bombing campaign against the North Korean airbase at Tok-ch'on at the start of the Korean War. Two RAF squadrons attempted to slow the North Korean offensive by bombing their aircraft at their base at Tok-ch'on, and the North Korean airbase was destroyed with their squadrons.

Operation
The United Kingdom was one of the countries that joined the United Nations coalition during the Korean War, and Prime Minister Clement Attlee committed the Royal Air Force to the war. RAF squadrons were deployed to Seoul at first, later moving to the captured town of Nampo as the front lines moved forwards. At the time of deployment in early July, American and South Korean forces were being pushed back to the Pusan Perimeter, and the RAF decided to launch a special operation to destroy the North Korean air force and slow the American advance. Two RAF squadrons were sent from Nampo to bomb the North Korean base at Tok-ch'on, and the Soviet-supplied North Korean planes were shot down in droves during the battle with the British fighters. Operation Chorus resulted in the destruction of all of the North Korean squadrons by 17 July 1950, just four days after the operation began. Chorus slightly slowed the North Korean advance, as they were without air support on the front lines. Although the effect was not immediately felt, it was a morale boost for the UN forces.
